How to Get the Perfect Clamp-On Muzzle Brake Fit for Your Shotgun?

 

A few things to consider before you measure your shotgun barrel.


1.  This guide only applies to you if you are purchasing a CLAMP-ON Muzzle Brake for a non-threaded shotgun.  The outside tip of your barrel should be smooth; if screw like threads are present on the outside tip of your threaded barrel, this guide does not apply to you.  Grizzly Gunworks Muzzle Brakes clamp onto the outside one inch of the barrel, so make sure that a front sight or magazine extension/ tube is not within the first one inch of your shotgun barrel.  Internal choke threads inside the barrel are not used to attach our Muzzle Brakes.


2. If you have a non-threaded barrel, ordering a CLAMP-ON Muzzle Brake saves time and hassle of a gunsmith; additionally saving the customer $100 - $160 by eliminating the need to thread the barrel.

If you are wondering what are the performance benefits of getting your muzzle threaded, there are none; it is only personal preference.  Grizzly Gunworks CLAMP-ON Muzzle Brake technology is superior, hence, it delivers equal performance to threaded Muzzle Brakes.  


3.  You MUST use CALIPERS - OR - a MICROMETER to take your measurements to 3 decimal places (e.g. 0.882 inches) or metric 2 decimal places (e.g. 22.35 mm).  Your CLAMP-ON Muzzle Brake is custom made to fit your barrel with precision and perfect alignment, hence accurate measurements are required.


MEASURE YOUR BARREL


A)  Take first measurement on the outside tip of your barrel......Example 0.880
